The old vehicle was used 100% for business so the system can handle that calculation. On the new vehicle, there is a window that asks "did you trade in another vehicle?". If I say yes (which is my situation), it asks "total cash or loan amount paid with trade-in". I interpreted this to be asking for the difference between the sales price of $39k and the trade-in of $20k giving an amount of $19k. The next window asks "what did you pay for the new vehicle?" and this is where I put the $39k. Are you saying that I should answer No to the trade in and not enter the $19k there?
